Modern freewheel for '78 Campy hub?

Looking for suggestions for a modern freewheel to use with a '78 Campy Record hub. Italian threaded. Looking for a range of 13-19 or 13-21, somewhere around there. Anyone used an IRD freewheel? Or should I just go the ebay route and look for something NOS?

The time I checked, IRD didn't make ratios that tight. The closest they currently offer is 13-24T.

IRD is not Italian threaded. You'll probably have to go 2d hand if you want to stick to Italian. Or you could thread an english threaded freewheel on your hub. You'll have to be careful as this will cut the threads a bit. Sutherlands says this is a "B" fit; it works but you will not want to go back to Italian after this. I did this recently on an old campy hub I wanted to keep using. It's working great.

Are you certain that your hub is Italian threaded?

Are you looking for 5, 6, or 7?

'78 hub is probably 120mm so only 5 or ultra 6 will fit, unless you use a longer axle.

From what I have found if you want to keep the price reasonable NOS/Vintage Italian is out the prices are just insane basically used junk is going for $100 and something nice could easily run a coupe of hundred. Your choices are to go with modern in a 6/7 speed english threaded to Italian and change the spacing and wheel dish. Another option to consider is going with a NOS Suntour Ultra 6, which would allow you to keep the spacing and gearing basically the same you can get one for about $50.

Looking for a 6 speed freewheel. As background, this is going on a backup clincher wheelset I recently built up for an old Proteus bicycle I'm slowly restoring. I'm certain the hub is Italian threaded.

Thanks for the suggestions - I'll start looking around the secondhand market for a suitable one. For now I'll try to match the threading.

Several SunTour 6-spd ultra-spaced freewheels on eBay, both new and used, but they're English thread.

I had no problem fitting a 'regular' spaced 6-spd SunTour freewheel to my old '75 Fuji.

You might want to contact forum member @pastorbobnlnh and see what he can do for you in an Italian thread freewheel...

finding an english freewheel will be much simpler. you won't be able to go back to an italian one, but that's no real loss.

here's ird's offerings: Classica 5/6/7-Speed Freewheels

they're out of the 6-speed 13-24, but you could go 7-speed nearly as easy. i've found a 9-speed chain works better with 7-speed freewheels. and they should fit 126mm drops the same as a 6.

my keepers all feature irds. for my flips and backups, i choose sunrace 14-28, because i have hills. they're only $15 on ebay.

i prefer new, ramped freewheels for their shifting ease, and i know none of the cogs will skip.

old freewheels are often potluck.

If you want used English threaded Suntour ultra-6, I may have a couple in ratios like that.

I recently reduced the good Pastor's inventory of Italian freewheels. If he can't help you out, Boulder Bicycle often has a decent inventory of vintage (albeit pricey) freewheels, including a few Italian-threaded ones.
